The engine is working well. Initial full power runs were up to 7500 rpm but
with a larger prop top rpm is down to 5500. Since I'm using an older Volvo
outdrive that probably never ran over 5000, I'm happier with this speed. My
speedometer now pegs at 24 knots (this is a heavy low speed hull). The
original 150 outboard never got it this fast. Plan to do some gps runs
later.
It is a real treat to not have to worry about cooling and noise. The stock
water cooled, underwater outlet does the trick.
Idling is now fine at 800 rpm but there is some hesitation going up through
about 1500 and occasionally seems to fire on one rotor at lower rpm.
